ELECTRICALLY-CONTROLLED VALVE.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed September 27, 1913.' SerialZNo. 792,194.

To all whom it may concern: I

Be it known that I, LEWIS A. MAPEL, a citizen of the United States ofAmerica, residing in the city of 'St. Louis and, State of Missouri, haveinvented certain new and useful Improvements in Electrically-Con-Another object is to provide improved .means for controlling a valvewhich is 'located in a liquid supply pipe, said'pipe being adapted-todischarge in't'oa receptacle when the valve is opened so that'the valvewill be automatically closed when the desired amount of water has beenobtained in the receptacle.

A further object is to provide improved means whereby a valve located ina supply pipe can be opened todifferent extents and when thepredetermined amount of liquid has passed by said valve, said valve is'alltomatically closed.

Other and further objects will appear in the s ecification, and hespecifically mentione in the appended claims, reference being' had tothe accompanying drawings exemplifying the invention, and in which, v

Figure 1 is a side elevation showing this improveddevice connected upwith a receptacle. Fig. 2 is an'enlarged fragmentary view showing thewater column tube in section, and a portion ofthe valve casing of thewater supply pipe broken away. Fig. 3 is an enlarged section taken onthe line III- III of Fig. 2.

Referring tothe drawings: 1 designates a receptacle to which isconnected a water column 2, said column communicating wgch e.- cured tosaid column 2, is a gage rod 4, said rod having slidablymounted thereona block 5, said block adapted to be adjustably held on said rod by theset-screw 6. Se-v cured to said block is an electrical contact 7, andpivotally mounted to said block at 8 is a contact lever 9, said contactpoints being located adjacent each other. Communicating with saidreceptacle 1 is a water supply pipe required,

10, and forming a part of said supply pipeis a valve housing 11, saidhousing having a preferably inclined valve seat 12 formed therein, inwhich is mounted a valve 13. Extendlng transversely and horizontallythrough said housing 11, and having its bearings in the outside of saidhousing, is a p1n14: Secured to said pin adjacent the center thereof andin the housing 11 is a lever 14', the end of said lever being connectedto the depending portion 15 of said valve 13 by the pivotal connection16. Mounted on one end of said pin 14, on the outside'of said housing11, is a hand lever 17, the hub portlon 18 of said hand lever havingformed thereon a series of ratchet teeth 19. Pivotally mounted at 20 toone side of said housmg 11 is a lever 21, said lever.having formedthereon a pawl 22, and at the opposite end of said lever is mounted amagnet attracting portion 23. Depending from the under slde of saidhousing 11 is a bracket 24, said brackethaving secured thereto anauxiliary bracket 25. Secured to said bracket 25 are apair of verticallymounted magnets 26, the upper ends of said magnets being locatedadjacent the under side of said magnet attracting portion 23 of saidlever'21.

Pivotally mounted at 27, to the bracket 25 is a lever 28, and secured tosaid bracket adjacent one end of said lever 28, is an electrical contact29. Pivotally mounted at 30 tothe lever 21 is a link 31, the oppositeend of said link being pivotally mounted at 32 to the lever 28, formedin said link 31. At the end, which ,is connected to the pivot 30 is anelongated opening 33. Secured to said lever 21 is one end of a coilspring 34, the opposite end of said spring being connected to thehousing 11. Electrically connected to the contact point 9 is a wire 35,the opposite end of said wire being connected to the lever 28.

Leading from magnets 26, is a the contact 29 to one of thewire 36, andleading from 37 is a wire 38. Leading from the contactpoint 7 to one ofthe line wires 37 is a wire. 39. Movably mounted in the column 2 is afloat-40, said float having verticall mounted therein a push-rod 41.

This improved device is used more as:- pecially where large amountsof'water are said amounts having to be regulated in accordance withprescribed amounts to be obtained in the receptacle 1, this amount ofwater being predetermined, the sliding block 5 is set in accordancetherewith on the gage-rod 4, The hand lever 17 is then manipulated, andthe valve 13 is elevated from its seat 12. The water in the supply pipe10 will then pass under the valve and into the receptacle 1. As thewater rises in said receptacle, the same water level will be attained inthe column 2.

n. The rising of the water in the receptacle will elevate the fioat 40in the column 2, thus carrying the rod 41, and the upper end thereofwill contact with and lift the contact lever 9 until said lever engagesthe contact 7 This contact of said contacts 7 and 9 will energize thecircuit in which this improved device is located, thus energizing themagnets 26 and drawing down the portion 23 of the lever'21, whichmovement will elevate the pawl 22 from the ratchet teeth 19. Thiselevating of the pawl 22 will unlock the elevated position of the valve13, and the pressure of the water in the supply pipe 10 hearing againstthe upper side of said valve 13 will immediately seat said valve on itsseat 12, thus closing off further discharge into the receptacle 1. Asthe lever 21 was being drawn down by the magnets 26, the pivot 30 ofsaid link 31 moved freely in the elongated opening 33. But before thecontact portion 23 of said lever 21 engaged said magnets 26, said pivot30 reached the lower end of the opening 33, and the link 31'was moveddownwardly. This movement of said link 31 displaced the lever 28 fromcontact with the contact 29, which movement of said lever 28 from saidcontact 29 denergized the circuit. The lever 21 would then be returnedto its normal position by the spring 34.
